Hi,
I stumbled upon a recursion overflow crash in BASH. It affects both my

Yes, you created an infinitely recursive script. It's a race to see whether
you exceed your stack or VM resource limit first. Since you're not
executing within a shell function, FUNCNEST has no effect.
There's a slim chance this might be exploitable.
I'm skeptical.
